Question

If the mean of the data below is 3.8, find m
x 1 2 3 4 5 6
f 1 4 7 m 6 3​

Answer 1

m = 1.8

Explanation:

Given data is as follows :

x 1 2 3 4 5 6

f 1 4 7 m 6 3​

We need to find the value of m if the mean of the data is 3.8.

Mean = sum of observations/no. of observations

So,

`3.8=(1+4+7+m+6+3)/(6)\\\\22.8=21+m\\\\22.8-21=m\\\\m=1.8`

So, the value of m is equal to 1.8.
